PUMP ANTIFREEZIN G ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 19, 19118.

Application filed June 5, 1917. Serial No. 172,875.

To all whom it may concern:

Be it remembered that I, WALTER J1m- KINS, a citizen of the UnitedStates, residing in Madison township, in the county of Riley and Stateof Kansas, have invented certain new and useful Improvements in PumpAntifreezing Attachments, of which the following is a specification,reference being had to the accompanying drawings, which form a parthereof.

My invention relates to improvements in attachments for preventing thewater from freezing in pumps and the object is to so construct such adevice that it may be readily attached to the pipe connected with anordinary pump and operated from above the surface of the ground orplatform.

I attain this object by means of the mechanism hereinafter described andillustrated in the accompanying drawings in which,-

Figure l is a view of a vertical section of pipe with my inventionattached;

Fig. 2, a view of the plate and mechanism on reverse side of the pipeshown in Fig. 1;

Fig. 3, a side view of my device attached to the pipe broken away at thevent with the plug in position to close the same when released;

Fig. 4, a horizontal sectional view of my device through w-w of Fig. 2.

Similar numerals of reference indicate like parts throughout the severalviews.

The well-pipe 1 is provided with an ordinary vent 8 at a sulficientdistance below the surface of the ground to permit the escape of allwater above the freezing point. To said pipe 1, by means of clevises 2,is secured plate 3 provided with slot 4 and to which, at 6, is securedone end of strapspring 5. A plug or stopper 7, preferably of a resilientmaterial, is secured to the under surface of said spring near itsfarther end and positioned opposite to the vent 8. To said plate 3, bymeans of recessed straps 9 and across the slot 4:, is secured crank 10to which crank and beneath said spring is secured the eccentric block 11in such a po sition as to allow the plug 7 to close said vent when atrest and to raise said spring and withdraw said plug when said crank andblock are given a half turn. This is accomplished by means of rod 12pivotally secured to wrist 13 of crank 10. Said rod being extended abovethe surface or platform enables the person to readily operate my device.The method of operation is ob vious.

Some of the advantages of my invention are its simplicity ofconstruction and attachment, its effectiveness, and its easy operationfrom the platform.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is A device of the class described comprising apipe provided with a vent a slotted plate secured to said pipe, a plugin alinement with the slot in said plate and with said vent, means forautomatically forcing said plug into said vent, a block eccentricallysecured to a shaft journaled in said plate, means for revolving saidblock to remove said plug from said vent and to release the same.
